Thanks to smartphones, it's easier than ever to keep a detailed food log no matter where your day takes you.

Calorific

Calorific

If numbers aren't your thing, or you find yourself getting overly involved with counting calories, this is the app for you. Calorific divides foods into three categories (red, yellow, and green — just a traffic light), and then into portion sizes for easy two-click tracking. There's no need to comb through overly involved databases to write down every minute meal detail, and Calorific uses your data to generate pie charts showing the healthy to unhealthy ratio of your food choices as well as the time of the day you make the best nutrition choices.

The Eatery

The Eatery

The rise of Instagram has taught us one key fact: People love snapping and sharing pictures of food. Why not put your friends' eyeball time to use by having them help analyze those food snaps? The Eatery lets you upload photographs of your food so other users can comment, like, share, and rate it on a scale of fat to fit. If you're more of a private food logger, you don't need to rely on the advice of others; the app provides all users with overviews of eating strengths and weaknesses, when they make the best and worst food decisions, and suggestions about how to improve your healthful intake.
